Btrfs: sysfs: move super_kobj and device_dir_kobj from fs_info to btrfs_fs_devices
This patch will provide a framework and help to create attributes from the structure btrfs_fs_devices which are available even before fs_info is created. So by moving the parent kobject super_kobj from fs_info to btrfs_fs_devices, it will help to create attributes from the btrfs_fs_devices as well. Patches on top of this patch now will be able to create the sys/fs/btrfs/fsid kobject and attributes from btrfs_fs_devices when devices are scanned and registered to the kernel. Just to note, this does not change any of the existing btrfs sysfs external kobject names and its attributes and not even the life cycle of them. Changes are internal only. And to ensure the same, this path has been tested with various device operations and, checking and comparing the sysfs kobjects and attributes with sysfs kobject and attributes with out this patch, and they remain same.
